Overview

Over the last decade, PlanetMath developed a large mathematical encyclopedia -- you can browse this via the Articles link at left. In 2013, we added support for Problems and Questions. The idea with these new features is to make PlanetMath more useful for students, and improve the encyclopedia as we go. We also have Collections you can use to organize articles and problems into course packets or reading lists, and Groups you can use for focused collaboration. More features are developing all the time -- please get in touch via the forum with any bug reports or feature requests. The FAQ has more information on site features.

*: Problems and solutions (p/s), and questions and answers (q/a) were introduced in early 2013, when we switched to the new platform. We also took the opportunity to drop users who had never contributed.
